Answer:
5) The parents phenotypeis tall because they are both Tt. The T is the dominant trait.
6)25% will be TT
-because only 1 of the four squares is TT
7) 50% will be Tt
- because 2 of the four squares is Tt
8) 25% will be tt
- beacuse 1 one 4 squares is tt
9) 75% of offspring will be Tall
- because T is domanint and 3 of the 4 sqaures has T
10) 25% of off pring will be short
-Because t is recesive and only 1 of the 4 sqaures has both tt. You need two recesive genes to have that trait
Hope this helps

Answer:
Cells, like humans, cannot generate energy without locating a source in their environment. However, whereas humans search for substances like fossil fuels to power their homes and businesses, cells seek their energy in the form of food molecules or sunlight. In fact, the Sun is the ultimate source of energy for almost all cells, because photosynthetic prokaryotes, algae, and plant cells harness solar energy and use it to make the complex organic food molecules that other cells rely on for the energy required to sustain growth, metabolism, and reproduction (PIC 1).
Cellular nutrients come in many forms, including sugars and fats. In order to provide a cell with energy, these molecules have to pass across the cell membrane, which functions as a barrier — but not an impassable one. Like the exterior walls of a house, the plasma membrane is semi-permeable. In much the same way that doors and windows allow necessities to enter the house, various proteins that span the cell membrane permit specific molecules into the cell, although they may require some energy input to accomplish this task (PIC 2).

First of all, only hermaphrodites can produce offspring by themselves, and most of the time, they end up being genetically mutated, but either way it is called asexual reproduction
